Traffic flow forecasting has complex spatial correlation and time dependence. Most current research models are based on a predefined graph structure with a priori knowledge for prediction, which cannot well extract the hidden spatial relationships in traffic data. In this paper, we propose the Optimal Graph Information Fused Graph Attention Network (OGIF-GAT). Specifically, we learn the actual connections between nodes and the hidden spatial relationships through the multigraph feature fusion structure. Next, we design a new graph attention network (GAT), which improves the problem of ignoring edge features in the graph structure in the traditional GAT model and considers their edge features when estimating the correlation of each neighboring node pair: the effect that the distance factor between neighboring nodes has on the spatial correlation. In addition, we use the temporal hybrid transformer (THT) to learn temporal dependencies. Extensive experiments on four public transportation datasets (PeMS04, PeMS08, PeMS-BAY, and METR-LA) demonstrate that our model achieves the optimal level of traffic flow prediction accuracy on all of them and is shown to have strong generalization ability.

This is especially important when planning a new bus line or re-routing an existing one. This paper aims to identify a simple model for predicting fuel consumption in suburban bus transport based on commonly available input data based on local conditions. The article deals with the issue of fuel consumption of a bus with a conventional compression ignition engine operating on suburban bus lines in a predetermined region in Slovakia. The selected indicators related to the operation of the studied bus are analysed, including the average speed of the bus, the average distance between stops, the road profile of the line and the ambient air temperature. The study was conducted using both long-term and short-term measurements, allowing for a comprehensive analysis of the data. Linear regression and polynomial regression were employed to determine the relationship between fuel consumption and the input data. The results of the long-term experimental measurements and regression analysis indicate that a second-degree polynomial regression is the most accurate method for predicting fuel consumption in suburban bus transport when considering the ambient air temperature. Short-term experimental measurements and regression analysis also demonstrate that a second-degree polynomial regression is the most effective approach for predicting fuel consumption in suburban bus transport, incorporating the average slope of the bus route and the average distance between bus stops. Average vehicle speed did not have a significant effect on predicting bus fuel consumption due to specific reasons that affect average velocity in very different ways.</p>\u0000 </div>","PeriodicalId":50259,"journal":{"name":"Journal of Advanced Transportation","volume":"2025 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/atr/2567720","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Distinguishing between the travel choice behaviors of passengers who board the first arriving train (Type I passengers) and those who are left behind (Type II passengers) in passenger assignment is essential for effective URT passenger management. This paper proposes a data-driven passenger-to-train assignment model (DPTAM) that leverages automated fare collection (AFC) data and automated vehicle location (AVL) data to differentiate between the travel choice behaviors of the two types of passengers. The model comprises two modules based on passenger travel choice behavior: the passenger route choice model (PRCM) and the passenger itinerary choice model (PICM). The PRCM employs a granular ball–based density peaks clustering (GB-DP) algorithm to estimate passengers’ route choices based on historical data, enhancing precision and efficiency in passenger classification and route matching. The PICM incorporates tailored itinerary selection strategies that consider train capacity constraints and schedules, enabling accurate inference of passenger itineraries and localization of their spatiotemporal states. The model also estimates train loads and left-behind probabilities to identify congested periods and sections. The effectiveness of DPTAM is validated through synthetic data, demonstrating superior assignment accuracy compared to benchmarks. Additionally, real-world data from Chengdu Metro reveal the impact of congestion on travel behavior and effectively identify congested periods and high-demand stations and sections, highlighting its potential to enhance URT system efficiency and passenger management.</p>\u0000 </div>","PeriodicalId":50259,"journal":{"name":"Journal of Advanced Transportation","volume":"2025 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/atr/6620828","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143880163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Concerning this, strategies such as setting speed limits, traffic calming measures, police enforcement, and spot speed camera enforcement (SSCE) have been widely investigated for their suitability and impacts on speed management. Although such conventional measures are effective, depending on circumstances, in reducing vehicle speed in the vicinity of the interventions, studies have shown that their impact is limited in space, leading to the problem of event migration. The promising approaches to solving such limitations are the use of variable speed limits (VSLs), intelligent traffic calming devices, sectional speed enforcement systems (SSES), and intelligent speed adaptation (ISA) systems.
